Description

Technical Field

[0001] This invention relates to the field of steel product shearing machines, specifically a steel product shearing machine for reactor processing. Background Technology

[0002] A reactor is a device used to realize a reaction process and is widely used in chemical, oil refining, and metallurgical fields. In the manufacturing process of reactors and other equipment, a large number of medium and thick steel plates are used as blanks for the cylinder, head, and nozzle. Before rolling and welding, the steel plates need to be cut into the required size and width by a shearing machine. Steel products for reactors usually have many specifications and significant differences in thickness between batches, so the requirements for the cross-sectional quality, straightness, and consistency of subsequent forming and welding are extremely high.

[0003] Most existing steel shearing machines use fixed or manually adjustable blade gaps between the upper and lower blades. When shearing steel plates of different thicknesses, operators must first measure the plate thickness based on experience or by stopping the machine, and then manually adjust the gap by turning the adjusting screw or eccentric mechanism. The entire adjustment process is manual, time-consuming, and it is difficult to guarantee that the gap value falls within a reasonable range, which is usually 2% to 9% of the plate thickness. If the blade gap is set too large during shearing, the plate is easily torn during shearing, resulting in obvious burrs, curled edges, and collapsed corners on the cut surface, affecting the quality of subsequent splicing and welding. If the blade gap is set too small, it will aggravate blade wear, increase shearing resistance, and even cause problems such as blade jamming and equipment overload, shortening the life of the blades and equipment.

[0004] Although some existing shearing equipment is equipped with a gap adjustment mechanism, its adjustment is still an offline mode of measurement first and then setting, which cannot adaptively adjust in real time according to the change of plate thickness during continuous feeding. Moreover, existing shearing machines do not have an automatic locking mechanism after the lower blade is adjusted. During the shearing process, the lower blade is subjected to large lateral impacts and vibrations. The lower blade is prone to slight displacement or rebound under the force, resulting in inconsistent gaps of the same batch of workpieces, reduced shearing repeatability accuracy, and thus affecting the overall processing quality of reactor components. Summary of the Invention

[0005] The purpose of this invention is to provide a steel shearing machine for reactor processing, so as to solve the problems mentioned in the background art.

A return disc spring is sleeved on the outside of the lower end of each slide rod. The two ends of the return disc spring abut against the extension and the lifting sensing frame, respectively. A transmission rod is symmetrically fixedly connected to both ends of the round shaft. The transmission rod is movably inserted into an adjacent movable slot.

[0012] As a further embodiment of the present invention, two locking mechanisms are symmetrically installed at both ends of the transmission plate, and the shearing machine body is symmetrically provided with shrinkage grooves. The two shrinkage grooves are symmetrically installed at both ends of the translation groove. The locking mechanism includes a locking component movably installed in the shrinkage groove. A hydraulic locking component and an electromagnetic locking component are installed on the side of the locking component, and a connecting mechanism is installed on the upper end of the hydraulic locking component. The locking assembly includes a push plate that is slidably installed in the shrinkage groove. A fastening block is fixedly connected to the side of the push plate near the transmission plate.

Locking seats are symmetrically fixedly connected to both ends of the transmission plate. The sides of the fastening block and the locking seats that are close to each other are both slopes, and the two slopes are compatible.

[0013] As a further embodiment of the present invention, the electromagnetic locking assembly includes a magnetic block fixedly connected to the side of the push plate away from the fastening block. A positioning disc spring is sleeved on the outer side of the magnetic block. The two ends of the positioning disc spring abut against the push plate and the shrinkage groove, respectively. The positioning disc spring applies elastic force to the push plate. An electromagnet is fixedly installed on one inner sidewall of the shrinkage groove away from the push plate. The working end face of the electromagnet extends into the positioning disc spring and is aligned with the magnetic block. A normally open push button switch for controlling the start and stop of the electromagnet is fixedly installed on the inner sidewall of the shearing machine body.

[0014] As a further embodiment of the present invention, the hydraulic locking assembly includes an L-shaped cylinder fixedly inserted into the feeding table of the main body of the shearing machine. The lower end of the L-shaped cylinder extends into the shrinkage groove. The L-shaped cylinder is divided into a vertical cylinder body and a horizontal cylinder body. A first piston and a second piston are slidably installed in the vertical cylinder body and the horizontal cylinder body of the L-shaped cylinder, respectively. Hydraulic oil is filled between the first piston and the second piston. A first piston rod is fixedly connected to the upper surface of the first piston. A first limiting ring and a second limiting ring are fixedly sleeved on the outside of the first piston. A second piston rod is fixedly connected to the side of the second piston.

[0015] As a further embodiment of the present invention, the connecting mechanism includes a lifting seat disposed between the first limiting ring and the second limiting ring, and a U-shaped groove is provided on one side of the lifting seat, and the lifting seat is locked outside the first piston rod through the U-shaped groove; A trigger head is fixedly connected to the upper surface of the lifting seat. A support rod is inserted through the upper end of the lifting seat from top to bottom. A lower positioning ring is fixedly sleeved on the lower end of the support rod. The upper end of the support rod is fixedly connected to the lifting frame. An upper positioning ring is fixedly sleeved on the upper end of the support rod. A locking spring is sleeved on the outside of the support rod. The two ends of the locking spring abut against the lifting seat and the upper positioning ring, respectively.

[0016] The beneficial effects of this invention are: 1. Through the ingenious linkage between the sensing mechanism and the purely mechanical drive mechanism, the equipment can provide real-time feedback on the thickness of the plate during continuous feeding. Based on the thickness of the plate, it can automatically adjust the gap between the upper and lower blades, eliminating the tedious process of manually adjusting the blades after stopping the machine. It is especially suitable for batch processing of reactor steel products with multiple specifications and varying thicknesses.

[0017] 2. By automatically adjusting the lower blade position, the lateral gap between the two cutting edges of the upper and lower blades is always maintained within the optimal range of 2% to 9% of the plate thickness, avoiding tearing, burrs, and curling caused by excessive gap, as well as tool wear, jamming, and high energy consumption caused by insufficient gap; through the cooperation of the contact wheel and the reset disc spring structure, the contact wheel is always in contact with the plate surface, with continuous response, good stability, and high precision.

[0018] 3. The hydraulic locking component and the electromagnetic locking component in the locking mechanism work together to ensure the stability of the shearing equipment. The lifting stroke of the lifting frame is cleverly used as a control signal to unlock during feeding adjustment and lock automatically during shearing. This ensures that the lower blade does not shift or shake when subjected to lateral impact during the shearing process, and the repeatability and positioning accuracy are high.

[0019] 4. The system combines pure mechanical sensing with hydraulic locking, resulting in a fast response and strong anti-interference capability. The thickness sensing and gap adjustment components utilize pure mechanical gear, rack, and thread transmission to linearly and amplify minute changes in plate thickness into downward cutting displacement. This provides high adjustment resolution, a compact structure, rapid response, and immunity to interference from complex electromagnetic environments in the workshop. The locking component combines electromagnetic control with hydraulic transmission, providing a large, stable, and reliable locking force. The overall design is highly industrially practical and reliable. By controlling the appropriate gap, the impact and wear on the cutting edge are reduced. The same equipment can stably process steel plates of various thicknesses, making it suitable for scenarios involving frequent changes in steel plate specifications during reactor manufacturing.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 12 This invention provides a technical solution: a steel product shearing machine for reactor processing, comprising a shearing machine body 1, a lifting frame 102 mounted on the upper end of the inner side of the shearing machine body 1 via a hydraulic device, an upper blade 103 fixedly mounted on the lower end of the lifting frame 102 via a blade holder, the hydraulic device being fixedly mounted on the upper end of the shearing machine body 1, a plate 101 being provided on the feeding platform of the shearing machine body 1, the plate 101 rolling along the guide rollers on the feeding platform to complete the normal conveying of the plate 101, the lower end of the output end of the hydraulic device being fixedly connected to the lifting frame 102, the output end of the hydraulic device driving the lifting frame 102 to move up and down; the hydraulic device is existing equipment, and how to control the shearing operation is also existing technology well known to those skilled in the art, and will not be described in detail here; A lower blade 21 is provided on the inner side of the shearing machine body 1 below the upper blade 103. A reasonable blade gap is left between the upper blade 103 and the lower blade 21. A transmission mechanism is installed on the side of the lower blade 21. A pressing mechanism is symmetrically installed at both ends of the transmission mechanism. Both the transmission mechanism and the pressing mechanism are installed inside the shearing machine body 1. A sensing mechanism is installed on the front side of the shearing machine body 1. The sensing mechanism contacts the top of the plate 101 and provides real-time feedback on the thickness of the plate 101. A drive mechanism is symmetrically installed at both ends of the sensing mechanism. The two drive mechanisms are respectively connected to the adjacent extrusion mechanism. The drive mechanism drives the extrusion mechanism to move. The extrusion mechanism pushes the transmission mechanism and the lower blade 21 to move, thereby adjusting the position of the lower blade 21 and thus adjusting the blade gap between the upper blade 103 and the lower blade 21. When the thickness of the sheet 101 changes, the sensing mechanism can detect and respond promptly. The sensing mechanism then drives the drive mechanism to oscillate, adjusting the position of the lower blade 21 to maintain a reasonable blade gap between the upper blade 103 and the lower blade 21. The blade gap specifically refers to the lateral distance between the two cutting edges; a reasonable blade gap is 2% to 9% of the sheet thickness. Locking mechanisms are symmetrically installed at both ends of the transmission mechanism, and the two locking mechanisms are installed on the main body 1 of the shearing machine.

[0024] A pressure device is installed above the feeding table inside the main body 1 of the shearing machine. The pressure device presses the plate 101 before shearing to prevent the plate 101 from shifting during the shearing process. A rear gauge is installed on the rear side inside the main body 1 of the shearing machine. The rear gauge is positioned mechanically or by CNC, thereby controlling the shearing length of the plate 101. An inclined feeding guide frame is installed on the rear side of the main body 1 of the shearing machine, below the rear gauge. The sheared plate segments slide down along the feeding guide frame.

[0025] The shearing machine body 1 has a translation groove 11 inside. The translation groove 11 is open on the rearward side. The transmission mechanism includes a transmission plate 2 that is slidably installed in the translation groove 11. One side of the transmission plate 2 extends through the translation groove 11 to the outside and is fixedly connected to the lower blade 21. The transmission plate 2 supports and limits the lower blade 21. The transmission plate 2 and the lower blade 21 are detachably connected. A T-shaped plate 26 is fixedly connected to the side of the transmission plate 2 away from the lower blade 21. Inclined surfaces 27 are symmetrically arranged at both ends of the T-shaped plate 26. Multiple reset mechanisms are installed equidistantly on the transmission plate 2. The reset mechanisms are installed in the translation groove 11.

[0026] Multiple grooves 22 are equidistantly provided on the side of the transmission plate 2 near the lower cutter 21. Multiple reset mechanisms are respectively installed in the multiple grooves 22. Each reset mechanism includes a fixing block 23 disposed in the groove 22. The fixing blocks 23 are all fixedly connected to the translation groove 11. The transmission plate 2 is slidably connected to the fixing blocks 23 through the grooves 22. A round rod 24 is inserted through the side of the fixing block 23. The round rod 24 is slidably connected to the fixing block 23. One end of the round rod 24 is fixedly connected to the inner side wall of the groove 22. A return spring 25 is sleeved on the outer side of the round rod 24. The two ends of the return spring 25 are fixedly connected to the fixing block 23 and the groove 22 respectively. The return spring 25 applies a pulling force to the transmission plate 2, so that the transmission plate 2 maintains the tendency to move outward toward the translation groove 11.

[0027] When the thickness of the sheared plate 101 increases, the two extrusion mechanisms move closer to each other. The extrusion mechanism extrudes the T-shaped plate 26 and pushes the T-shaped plate 26 towards the innermost side of the translation groove 11. The T-shaped plate 26 drives the lower blade 21 to move closer to the translation groove 11 through the transmission plate 2, so that the lower blade 21 moves away from the upper blade 103, thereby increasing the blade gap between the upper blade 103 and the lower blade 21. When the transmission plate 2 moves, it will stretch the return spring 25, and at the same time, the transmission plate 2 will drive the round rod 24 to slide along the fixed block 23; When the thickness of the sheared plate 101 becomes thinner, the two extrusion mechanisms move away from each other. The extrusion mechanism releases the extrusion and push on the T-shaped plate 26. Under the action of the pull force of the return spring 25, the transmission plate 2 is pulled to slide towards the outside of the translation groove 11. The transmission plate 2 drives the lower blade 21 to move closer to the upper blade 103, thereby reducing the blade gap between the upper blade 103 and the lower blade 21. By coordinating the extrusion mechanism and the reset mechanism, the blade gap between the upper blade 103 and the lower blade 21 can be adjusted according to the thickness of the plate 101, so that the blade gap between the upper blade 103 and the lower blade 21 is within a reasonable range, ensuring the accuracy and quality of shearing.

[0028] The extrusion mechanism includes an extrusion block 28 symmetrically slidably installed in the translation groove 11. An extrusion inclined surface is provided on the side of the extrusion block 28 near the inclined surface 27. The extrusion inclined surface is adapted to the inclined surface 27 and slides in contact with the inclined surface 27.

[0029] When the two extrusion mechanisms move closer to each other, the extrusion ramp on the side of the extrusion block 28 slides along the inclined surface 27, and pushes the inclined surface 27 to move through the extrusion ramp, thereby causing the T-shaped plate 26 to move toward the innermost side of the translation groove 11. When the two extrusion mechanisms move away from each other, the extrusion slope on the side of the extrusion block 28 gradually reduces the extrusion force on the inclined surface 27. At this time, under the action of the pull force of the return spring 25, the transmission plate 2 slides outward along the translation groove 11.

[0030] The bottom of the translation groove 11 is provided with a sliding groove 12, and cylindrical rotating grooves 14 are symmetrically provided at both ends of the sliding groove 12. The feeding table of the shearing machine body 1 is symmetrically provided with swing grooves 13. The two swing grooves 13 pass through the adjacent rotating grooves 14 respectively. The lower ends of the two drive mechanisms are respectively installed in the two swing grooves 13, and the sensing mechanism is installed between the two drive mechanisms.

[0031] The drive mechanism includes a bent swing frame 4 slidably installed in the swing groove 13. A mounting plate 41 is rotatably mounted on the bent portion of the bent swing frame 4 via a rotating shaft. The lower end of the mounting plate 41 is fixedly connected to the upper surface of the feed table. The upper end of the bent swing frame 4 is outside the swing groove 13, and the lower end extends into the swing groove 13. A movable groove 42 is provided at the end of the bent swing frame 4 outside the swing groove 13. A fan-shaped toothed plate 43 is fixedly connected to the end of the bent swing frame 4 inside the swing groove 13. The fan-shaped toothed plate 43 is coaxial with the rotating shaft. Both the bent swing frame 4 and the fan-shaped toothed plate 43 are movable. Installed in the swing groove 13, a transmission gear 44 is meshed below the sector tooth plate 43. An internal threaded sleeve 45 is fixedly installed through the side of the transmission gear 44. Both the transmission gear 44 and the internal threaded sleeve 45 are coaxial with the rotating groove 14. The internal threaded sleeve 45 is rotatably connected to the rotating groove 14 through a bearing. A threaded rod 46 is installed through the inner side of the internal threaded sleeve 45. The threaded rod 46 is threadedly connected to the internal threaded sleeve 45. One end of the threaded rod 46 extends into the slide groove 12 and is fixedly connected to a slide plate 47. The slide plate 47 is slidably connected to the slide groove 12. The upper surface of the slide plate 47 is fixedly connected to the adjacent extrusion block 28.

[0032] When the thickness of the sheared plate 101 increases, the plate 101 pushes the sensing mechanism to move upward, the sensing mechanism pushes the upper end of the bending swing frame 4 to swing upward, and at the same time the lower end of the bending swing frame 4 drives the fan-shaped toothed plate 43 to swing upward. The fan-shaped toothed plate 43 drives the transmission gear 44 and the internal threaded sleeve 45 to rotate. The internal threaded sleeve 45 pushes the threaded rod 46 to move into the slide groove 12. The threaded rod 46 drives the slide plate 47 to move. The slide plate 47 drives the extrusion block 28 to slide along the translation groove 11, so that the two extrusion blocks 28 move closer to each other, and the lower blade 21 moves closer to the translation groove 11, thereby increasing the blade gap between the upper blade 103 and the lower blade 21. When the thickness of the sheared plate 101 becomes thinner, the sensing mechanism moves downward, and the sensing mechanism pushes the upper end of the bending swing frame 4 to swing downward. At the same time, the lower end of the bending swing frame 4 drives the fan-shaped toothed plate 43 to swing downward. The fan-shaped toothed plate 43 drives the transmission gear 44 and the internal threaded sleeve 45 to rotate in opposite directions. The internal threaded sleeve 45 pushes the threaded rod 46 to move into the rotating groove 14. The threaded rod 46 drives the slide plate 47 to move. The slide plate 47 drives the extrusion block 28 to gradually release the extrusion on the T-shaped plate 26. At this time, under the action of the return spring 25, the lower blade 21 moves away from the translation groove 11, thereby reducing the blade gap between the upper blade 103 and the lower blade 21.

[0033] The sensing mechanism includes a lifting sensing frame 3 positioned between two bending swing frames 4. A round shaft 31 is inserted through the lifting sensing frame 3, and the round shaft 31 is rotatably connected to the lifting sensing frame 3 via bearings. Multiple touch wheels 32 are fixedly sleeved at equal intervals on the outside of the lifting sensing frame 3. Multiple slide rods 33 are fixedly connected at equal intervals on the upper surface of the lifting sensing frame 3. An extension is protruding from the front side of the shearing machine body 1. The upper ends of the multiple slide rods 33 all pass through the extension upwards and are fixedly sleeved with anti-detachment rings. The extension is slidably connected to the extension. Each slide rod 33 is fitted with a reset disc spring 34 on the outside of its lower end. The two ends of the reset disc spring 34 abut against the extension and the lifting sensor 3 respectively. The reset disc spring 34 applies a downward thrust to the lifting sensor 3, so that the lifting sensor 3 maintains the tendency to drive the round shaft 31 and the touch wheel 32 to move downward. The two ends of the round shaft 31 are symmetrically fixedly connected with transmission rods 35. The transmission rods 35 are movably inserted into the adjacent movable slots 42, and the transmission rods 35 are slidably connected to the movable slots 42.

[0034] The plate 101 passes under the touch wheel 32, and the lower end of the plate 101 moves along the guide roller on the feeding table, while the touch wheel 32 rolls along the upper surface of the plate 101. When the thickness of the sheared plate 101 increases, the plate 101 pushes the touch wheel 32 to move upward, the touch wheel 32 drives the round shaft 31 to move upward, the round shaft 31 drives the lifting sensor frame 3 and the transmission rod 35 to move upward synchronously, the lifting sensor frame 3 drives the slide rod 33 to slide along the extension, so that the lifting sensor frame 3 can move stably. At the same time, the lifting sensor frame 3 squeezes the reset disc spring 34, and when the transmission rod 35 moves upward, it slides along the movable groove 42. At the same time, the transmission rod 35 pushes the upper end of the bending swing frame 4 to swing upward. When the thickness of the sheared plate 101 becomes thinner, the lifting sensor 3 is pushed downward by the elastic force of the reset disc spring 34. The lifting sensor 3 drives the touch wheel 32 downward through the round shaft 31, so that the touch wheel 32 always rolls in contact with the upper surface of the plate 101. When the round shaft 31 moves downward, it drives the transmission rod 35 to move downward in sync. The transmission rod 35 pushes the upper end of the bending swing frame 4 to swing downward.

[0035] Two locking mechanisms are symmetrically installed at both ends of the transmission plate 2. Shrinkage grooves 15 are symmetrically opened inside the shearing machine body 1. Two shrinkage grooves 15 are symmetrically installed at both ends of the translation groove 11. The locking mechanism includes a locking component that is movably installed in the shrinkage groove 15. A hydraulic locking component and an electromagnetic locking component are installed on the side of the locking component. A connecting mechanism is installed on the upper end of the hydraulic locking component. The locking assembly includes a push plate 5 that is slidably installed in the shrinkage groove 15. A fastening block 51 is fixedly connected to the side of the push plate 5 near the transmission plate 2. One end of the fastening block 51 extends through the shrinkage groove 15 into the translation groove 11 and is slidably connected to the shearing machine body 1. Locking seats 29 are symmetrically fixedly connected to both ends of the transmission plate 2. The sides of the fastening block 51 and the locking seat 29 that are close to each other are both slopes, and the two slopes are compatible.

[0036] The fastening block 51 is located behind the bending swing frame 4, and the fan-shaped toothed plate 43 is located below the fastening block 51. The fastening block 51 will not hinder the normal swing of the bending swing frame 4 and the fan-shaped toothed plate 43.

[0037] When it is necessary to lock the transmission plate 2, the slope of the fastening block 51 is tightly abutted against the slope of the locking seat 29, and the locking seat 29 is firmly abutted by the fastening block 51, thereby completing the locking of the locking seat 29, and thus completing the locking of the transmission plate 2 and the lower blade 21. When it is necessary to adjust the position of the lower cutter 21, the fastening block 51 is separated from the locking seat 29, and the locking of the locking seat 29 is released, so that the position of the lower cutter 21 can be easily adjusted.

[0038] The electromagnetic locking assembly includes a magnetic block 52 fixedly connected to the side of the push plate 5 away from the fastening block 51. A positioning disc spring 53 is sleeved on the outer side of the magnetic block 52. The two ends of the positioning disc spring 53 abut against the push plate 5 and the shrinkage groove 15 respectively. The positioning disc spring 53 applies elastic force to the push plate 5. An electromagnet 54 is fixedly installed on one inner wall of the shrinkage groove 15 away from the push plate 5. The working end face of the electromagnet 54 extends into the positioning disc spring 53 and is aligned with the magnetic block 52. A normally open push button switch 66 for controlling the start and stop of the electromagnet 54 is fixedly installed on the inner wall of the shearing machine body 1.

[0039] A normally open push-button switch 66 is connected in series in the circuit of electromagnet 54. The contacts of the normally open push-button switch 66 are open when no external force is applied, and no current is conducted between the two terminals under normal conditions. An emergency stop controller, a power supply and protective components are also connected in series in the power supply circuit of electromagnet 54. The specific power supply circuit and control principle of electromagnet 54 are existing technologies well known to those skilled in the art, and will not be described in detail here.

[0040] When the normally open push button switch 66 is subjected to an external force, it is energized. After the external force is removed, the contacts of the normally open push button switch 66 return to the open state. When the normally open push button switch 66 is triggered and closed, the power supply circuit of the electromagnet 54 is turned on, and the electromagnet 54 is energized to generate electromagnetic attraction. At this time, the working end face of the electromagnet 54 generates an attraction force on the magnetic block 52, causing the magnetic block 52 to move closer to the working end face of the electromagnet 54. The magnetic block 52 drives the push plate 5 to move closer to the electromagnet 54 in sync. The push plate 5 drives the fastening block 51 away from the locking seat 29, thus completing the unlocking of the locking seat 29. As the push plate 5 moves closer to the electromagnet 54, it compresses the positioning disc spring 53, causing the positioning disc spring 53 to generate elastic force.

[0041] When the normally open push button switch 66 is turned off, the electromagnet 54 is de-energized. Under the action of the positioning disc spring 53, the push plate 5 moves away from the electromagnet 54. At the same time, the push plate 5 drives the fastening block 51 to move closer to the locking seat 29, so that the slope of the fastening block 51 is tightly abutted against the slope of the locking seat 29, thus completing the locking of the locking seat 29.

[0042] The hydraulic locking assembly includes an L-shaped cylinder 6 fixedly inserted into the feeding platform of the shearing machine body 1. The lower end of the L-shaped cylinder 6 extends into the shrinkage groove 15. The L-shaped cylinder 6 is divided into a vertical cylinder body and a horizontal cylinder body. The upper end of the vertical cylinder body extends above the feeding platform, and one end of the horizontal cylinder body extends into the shrinkage groove 15. A first piston 61 and a second piston 67 are slidably installed in the vertical cylinder body and the horizontal cylinder body of the L-shaped cylinder 6, respectively. Hydraulic oil is filled between the first piston 61 and the second piston 67. The first piston 61 is slidably installed in the vertical cylinder body, and the second piston 67 is slidably installed in the horizontal cylinder body. A first piston rod 62 is fixedly connected to the upper surface of the first piston 61. The upper end of the first piston rod 62 extends to the outside of the vertical cylinder. A first limiting ring 63 and a second limiting ring 64 are fixedly sleeved on the outside of the first piston 61. The first limiting ring 63 is located below the second limiting ring 64. A second piston rod 68 is fixedly connected to the side of the second piston 67. The end of the second piston rod 68 away from the second piston 67 extends to the outside of the horizontal cylinder. A pressing plate 69 is fixedly connected to the end of the second piston rod 68 away from the second piston 67. The pressing plate 69 is fixedly connected to the push plate 5.

[0043] The first piston 61 and the second piston 67 are both in a sealed sliding fit with the L-shaped oil cylinder 6, and the first piston rod 62 and the second piston rod 68 are both in a sliding connection with the L-shaped oil cylinder 6. The hydraulic oil is incompressible. The connecting mechanism includes a lifting seat 7 disposed between the first limiting ring 63 and the second limiting ring 64. A U-shaped groove 75 is provided on one side of the lifting seat 7. The lifting seat 7 is locked outside the first piston rod 62 through the U-shaped groove 75, and the lifting seat 7 and the first piston rod 62 are slidably connected up and down. A trigger head 65 is fixedly connected to the upper surface of the lifting seat 7. The trigger head 65 is located directly below the normally open push button switch 66. When the lifting seat 7 moves upward to the top, the trigger head 65 presses the contacts of the normally open push button switch 66, causing the normally open push button switch 66 to be triggered and closed. A support rod 71 is inserted through the upper end of the lifting seat 7 from top to bottom, and the support rod 71 is slidably connected to the lifting seat 7. A lower positioning ring 72 is fixedly sleeved on the lower end of the support rod 71. The upper end of the support rod 71 is fixedly connected to the lifting frame 102. An upper positioning ring 73 is fixedly sleeved on the upper end of the support rod 71. A locking spring 74 is sleeved on the outside of the support rod 71. The two ends of the locking spring 74 abut against the lifting seat 7 and the upper positioning ring 73 respectively, and the locking spring 74 applies a downward elastic force to the lifting seat 7.

[0044] Initially, the lifting frame 102 drives the connecting mechanism to the top. At this time, the support rod 71 pulls the lifting seat 7 to the top through the lower positioning ring 72. The lifting seat 7 drives the first piston rod 62 to move upward to the top through the second limit ring 64. At this time, the lifting seat 7 drives the trigger head 65 to apply force to the contacts of the normally open push button switch 66, so that the electromagnet 54 is activated. The electromagnet 54 applies attraction to the magnetic block 52. Through the magnetic block 52, the push plate 5 and the fastening block 51 are moved away from the locking seat 29. At the same time, the hydraulic locking assembly also drives the push plate 5 and the fastening block 51 away from the locking seat 29, thereby releasing the lock on the locking seat 29.

[0045] As the lifting frame 102 moves the support rod 71 downward, the lower positioning ring 72 at the lower end of the support rod 71 descends synchronously. At this time, under the action of the locking spring 74, the lifting seat 7 can descend synchronously with the support rod 71. The lifting seat 7 drives the trigger head 65 to move downward, causing the trigger head 65 to release the pressure on the normally open button switch 66 contact. The electromagnet 54 is de-energized, and the positioning disc spring 53 is unrestrained. Under the action of the positioning disc spring 53, the push plate 5 is pushed to move, so that the fastening block 51 abuts against the locking seat 29, thus completing the locking of the locking seat 29.

[0046] At the same time, the support rod 71 continues to descend, and the lifting seat 7 also continues to descend. While the push plate 5 moves, the second piston 67 is driven to move through the clamping plate 69 and the second piston rod 68. When the second piston 67 moves, the volume between the two pistons increases and generates negative pressure, which causes the first piston 61 to move downward a certain distance. At this time, the first piston 61 only descends and does not squeeze the hydraulic oil. When the lower surface of the lifting seat 7 contacts the first limiting ring 63, the upper blade 103 is above the plate 101 and the two are about to contact. The lifting frame 102 continues to move downward. At this time, the lower end of the lifting seat 7 is blocked by the first limiting ring 63 and cannot move downward. The support rod 71 drives the upper positioning ring 73 to move downward and compress the locking spring 74. Under the action of the elastic force of the locking spring 74, a downward elastic force is applied to the lifting seat 7, so that the lifting seat 7 applies a downward pushing force to the first limiting ring 63. The first limiting ring 63 applies a downward pushing force to the first piston 61 through the first piston rod 62. The first piston 61 compresses the hydraulic oil and transmits the compressing force to the second piston 67 through the hydraulic oil, so that the second piston 67 maintains the tendency to move outward. The second piston 67 drives the pressing plate 69 to apply a pushing force to the push plate 5 through the second piston rod 68, so that the fastening block 51 can be firmly locked with the locking seat 29 to prevent the lower blade 21 from shaking during the shearing process. As the lifting frame 102 moves downward, it drives the upper blade 103 to move downward, and the upper blade 103 and the lower blade 21 work together to cut the plate 101.

[0047] With the cooperation of two locking mechanisms, when the upper blade 103 moves to the uppermost initial position, the plate 101 is fed, and the locking of the transmission mechanism is released. At this time, the sensing mechanism can adjust the position of the lower blade 21 in real time according to the thickness of the plate 101, so as to ensure that the blade gap between the upper blade 103 and the lower blade 21 is reasonable when the upper blade 103 is cutting, and there will be no situation that is too wide or too narrow, thus ensuring the cutting accuracy and quality.

[0048] During shearing, two locking mechanisms work together to firmly lock the lower blade 21, ensuring the stability of the shearing process after the lower blade 21 is adjusted.

[0049] Working principle: The core of this shearing machine is a closed-loop control chain that integrates "thickness detection → gap adjustment → automatic locking", which is linked to the lifting action of the upper blade 103. The specific working process is as follows: Initially, the lifting frame 102 and the upper blade 103 are at the top, and the support rod 71 drives the lifting seat 7 to the top. The trigger head 65 presses the normally open button switch 66, the electromagnet 54 is energized and attracts the magnetic block 52, and the hydraulic locking assembly drives the push plate 5 to move backward, so that the fastening block 51 is separated from the locking seat 29. At this time, the transmission plate 2 connected to the lower blade 21 is in the unlocked free state, and the plate 101 can be normally fed between the feeding table and the sensing mechanism.

[0050] During shearing, the plate 101 is first passed under the contact wheel 32. Under the action of the return disc spring 34, the contact wheel 32 always rolls along the upper surface of the plate 101.

[0051] When the thicker plate 101 is replaced, the touch wheel 32 is lifted up. The touch wheel 32 pushes the lifting touch frame 3 and the transmission rod 35 to move upward synchronously through the round shaft 31. The lifting touch frame 3 squeezes the reset disc spring 34 and pushes the upper end of the bending swing frame 4 to swing upward through the transmission rod 35. When a thinner plate 101 is replaced, the touch wheel 32 moves down and presses against the upper surface of the plate 101 under the action of the return disc spring 34. At the same time, the round shaft 31 drives the transmission rod 35 to move down, so that the transmission rod 35 pushes the upper end of the bending swing frame 4 to swing down, thereby converting the change in the thickness of the plate 101 into the rotational swing of the bending swing frame 4.

[0052] The lower end of the bending swing frame 4 swings synchronously with the upper end. The swing of the bending swing frame 4 drives the fan-shaped toothed plate 43 at its lower end to swing synchronously. The fan-shaped toothed plate 43 drives the transmission gear 44 and the internal threaded sleeve 45 to rotate. The internal threaded sleeve 45 pushes the threaded rod 46 to move. The threaded rod 46 drives the extrusion block 28 to move through the sliding plate 47, thereby causing the two extrusion blocks 28 to move closer to or further away from each other. When the thickness of the plate 101 increases, the two extrusion blocks 28 move closer to each other. The extrusion slope on the side of the extrusion block 28 pushes the inclined surface 27 to move, thereby causing the T-shaped plate 26 to move toward the innermost side of the translation groove 11. The T-shaped plate 26 drives the lower blade 21 to move closer to the translation groove 11 through the transmission plate 2, so that the lower blade 21 moves away from the upper blade 103, thereby increasing the blade gap between the lower blade 21 and the upper blade 103. When the thickness of the sheet 101 becomes thinner, the two extrusion blocks 28 move away from each other. At this time, under the action of the pull force of the return spring 25, the transmission plate 2 is pulled to move outward along the translation groove 11. The transmission plate 2 drives the lower blade 21 to move closer to the upper blade 103, thereby reducing the blade gap between the lower blade 21 and the upper blade 103. The blade gap between the lower blade 21 and the upper blade 103 is automatically controlled within a reasonable range of 2% to 9% of the plate thickness.

[0053] During the shearing process, when the lifting frame 102 is driven down by the hydraulic device to shear, the lifting frame 102 drives the support rod 71 to move down, and the lifting seat 7 moves down accordingly. The lifting seat 7 drives the trigger head 65 to release the pressure on the normally open push button switch 66. At this time, the normally open push button switch 66 is disconnected, the electromagnet 54 is de-energized, and the positioning disc spring 53 is no longer restricted. Under the action of the elastic force of the positioning disc spring 53, the push plate 5 is pushed away from the electromagnet 54 and moves away from the electromagnet 54. The push plate 5 drives the fastening block 51 to abut against the slope of the locking seat 29. As the lifting frame 102 continues to descend, the push plate 5 drives the second piston 67 to move through the abutment plate 69 and the second piston rod 68, thereby pulling the first piston 61 down, so that the first piston rod 62, the first limiting ring 63 and the second limiting ring 64 move down synchronously. When the lower surface of the lifting seat 7 contacts the first limiting ring 63, the lifting seat 7 is held in place by the first limiting ring 63. At this time, the lifting frame 102 drives the support rod 71 to continue to move downward. The support rod 71 drives the upper positioning ring 73 to compress the locking spring 74. The locking spring 74 applies elastic force to the lifting seat 7. The lifting seat 7 transmits the elastic force to the push plate 5 through the hydraulic locking assembly. At the same time, through the positioning disc spring 53, the fastening block 51 and the locking seat 29 can be firmly abutted, thereby firmly fixing the lower blade 21 and preventing it from shaking during shearing.

[0054] After shearing is completed, the lifting frame 102 is driven by the hydraulic device to rise back to the top and unlock again. The next piece of board 101 is fed in and the gap is automatically adjusted according to its thickness to enter the next cycle. This process is repeated to continuously shear.
